What does a "spendthrift" clause do in a trust, and when does it matter?

A spendthrift clause restricts a beneficiary's ability to assign, sell, or pledge their future interest in the trust. It also prevents creditors from attaching the beneficiary's interest before distribution. It's a small piece of legal text with enormous protective power.

What it says (typical language):

"No beneficiary may anticipate, assign, encumber, alienate, or convey any income or principal of the trust before such income or principal is actually distributed to them. No creditor or other claimant of any beneficiary shall have any right to attach, levy upon, or garnish the trust corpus or distributions before actual distribution."

Three protections this provides:

1. Anti-assignment (squander protection):

Without a spendthrift clause, a beneficiary could sell their future interest in the trust for a discounted lump sum today. A 30-year-old beneficiary expecting to receive $10M over 30 years could potentially sell that interest to a "structured-settlement" buyer for $4M today.

With a spendthrift clause, this assignment is void. The structured-settlement buyer has no claim against the trust. Even if the beneficiary wants to sell, they can't.

2. Anti-attachment (creditor protection):

Without a spendthrift clause, a creditor with a judgment can serve a writ of garnishment on the trustee, claiming the beneficiary's future distributions. The trustee must comply with the writ.

With a spendthrift clause, the writ is unenforceable. The creditor has no claim until distribution actually happens — and the trustee has discretion to delay or redirect distributions.

3. Anti-encumbrance (loan protection):

Without a spendthrift clause, a beneficiary could pledge their future interest as collateral for a loan. If the loan defaults, the lender takes over the beneficiary's interest.

With a spendthrift clause, this collateral assignment is void. Lenders cannot take a security interest in a spendthrift trust beneficiary's interest.

When does it matter most?

• Young or financially unsophisticated beneficiaries (most common case)
• Beneficiaries in high-litigation professions
• Beneficiaries with substance abuse or gambling problems
• Beneficiaries who might be vulnerable to family pressure or scams
• Beneficiaries in unstable marriages (anticipating possible divorce)

Limits and exceptions:

The clause is not invincible. Even with a perfect spendthrift clause, creditors can sometimes reach trust assets:

• Mandatory distributions: if the trustee has no discretion (fixed distribution), the spendthrift clause may not block garnishment of distributions in transit. Some states allow it, others don't.
• Self-settled trusts: if the grantor is also a beneficiary, federal bankruptcy law (10-year look-back under 11 USC 548(e)) can pierce the protection.
• Government claims: child support, spousal support, federal tax liens, and government benefits-fraud claims can typically pierce spendthrift protection.
• Bankruptcy preference periods: for 90 days before filing (1 year for insiders), normal asset shielding may be unwound.
• Public policy exceptions: courts may pierce in egregious cases of fraud.

The "American Spendthrift Doctrine":

US courts have generally enforced spendthrift clauses for non-self-settled trusts since the late 1800s. This is more protective than English law, which originally did not enforce spendthrift restrictions. Most US states have spendthrift statutes codifying the doctrine.

Practical drafting:

A modern spendthrift clause:

• Names specific protections (anti-assignment, anti-attachment, anti-encumbrance)
• Includes "and any similar restrictions" catch-all language
• Specifies it survives bankruptcy
• Notes specific exceptions if any (e.g., "except for child support")
• Confirms enforceability under specified state law

Without a spendthrift clause:

Surprisingly, many older trust agreements (and some modern ones drafted carelessly) lack spendthrift clauses. This is a massive vulnerability. A trust without a spendthrift clause is essentially asking creditors to find it.

If you're reviewing a trust agreement and you don't see a spendthrift clause, that's a red flag. Modern wealth-management practice mandates them.

For the exam:

CFA L3 may ask about spendthrift clauses in trust-protection vignettes. Know:

• What the clause does (3 protections)
• When it's most valuable (young, vulnerable, litigation-exposed beneficiaries)
• Common exceptions (child support, taxes, bankruptcy preference periods)
• Always recommend its inclusion in modern trusts
